This invention relates to cartons, and'relates more particularly to cartons for packing cones or cheeses ofyarn.

An object of this invention is to provide a carton for cones or cheeses of yarn which will protect the same during shipping or storing.

Another object of this invention is the provision of an improved carton that is easily manufactured and readily filled.

A further object of this invention is to provide a collapsible partitioned carton which may quickly be arranged in its operative form and which maintains a fully closed order without the use of staples, adhesive tape or similar expedients.

Figure 2 is a plan view of a closed carton, with cones of yarn therein, made from the blank shown in Figure 1, and i Figure 3 is a perspective view, partially cut away to show the interior thereof, of a partially closed carton formed from the blank shown in Figure 1.

Like reference numerals indicate like parts throughout the several views of the drawing.

'Referring to Figures 1, 2 and 8 of the drawing, there is shown a modification of my invention which is particularly suitable for use in packing and shipping cones of yarn. In the carton illustrated in these figures, the cones of yarn are rigidly supported and packed so that they do not rub against each other, which rubbing would spoil or mar at least the outer convolutions of the yarn. The carton is arranged in a plurality of compartments in each of which a cone is positioned centrally thereof and held rigidly so as to prevent movement of the cone.

The blank for the cartons shown in Figures 1, 2 and 3 may be cut from paper, cardboard, thin metal or the like in any suitable manner as, for

example, by a die of the desired configuration,

figuration. Extending from a longitudinal edge of side sections 4 and 8 are members 'I and- 8, respectively, which consist of rectangular sections 9 and H which together form, in this modification, the bottom of the carton. The bottom sections 9 and II have integral therewith flaps l2 and i3, respectively,- which bend along fold-lines I4 and i5 and I6 and ii to form in the completed carton contiguous partitions which also act as bracing members. The flaps or partitions l2 and [3 are narrower than the cover sections 9 and H as is shown at l8 in Figure 1 of the drawing. The flaps or partitions l2 and B are provided with slots l9 and 2|, respectively, which slots in the assembled oa'rton are registeredwith each other and have a purpose which will hereinafter be described. To aid in assembling the carton the corners of the free longitudinal edge of flaps I2 and I3' are rounded as shown at 22, as are the corners of slots l8 and 2!,

The longitudinal edges of side sections 3 and 5 have integral therewith members 24 and 25, respectively, which are similar to members I and 8 and consist of rectangular sections 26 and 21 which together form the top of the carton. The top sections 26 and 21 have integral therewith flaps 28 and 29, respectively, which bend along,

fold-lines 3| and 32 to form in the completed carton contiguous partitions which also act as bracing members. The flaps or partitions 28 and 29 are provided with slots "and 34, respectively, which slots register with each other when the cover is closed. The flaps or partitions 28 and 28 are narrower than the top cover sections 26 and 21 as is shown at 35 in Figure l of the drawing. The corners of the free longitudinal edge of flaps 28 and 29 are rounded as shown at 3G to facilitate the assembling and closing of the carton.

As is shown in Figure 3 of the drawing, when the carton is closed the slots interlock and the flaps form crossed bracing members which cooperate to produce a substantially rigid construction.

When it is desired to employ the carton for the packaging of articles having protruding ends, such as cones of yarn shown by dotted lines 31 in Figure 2, holes 38 of substantially the same diameter as the large end of a cone core are provided in the bottom sections I and 8 and holes 39 of substantially the same diameter as the small end of a cone core are provided in the top rectangular sections 24 and 25. These holes may be of any desired shape and suitably positioned in the top and/or bottom rectangular "sections to accommodate any article being packed. The carton For aiding inthe opening up oi the carton, holes 4| may be provided into which the operator can hook his finger. Tabs or pulls may be employed as an alternative for the holes 4|.

In the first assembling of the carton the side wall edges 42 and 43 may be Joined by an adhesive or gummed tape 44. After-the first assembling oi the carton the same may be packed, unpacked and collapsed many times without dis- 3. A carton for packaging 01 articles, comprising tour side walls formed of a rectangular piece, bottom flaps extending from two opposite side walls a distance substantially equal to half the length of the other twosides and the height of the sides, top flaps extending in an opposite direction to the bottom flaps and from the side walls adjacent to the side walls having the bottom flaps, said top flaps extending a distance substantially equal to one-half the length of the side walls having the bottom flaps and the height of the side walls, slots centrally located in said bottom flaps and extending from the outer edge inturbing the joint. No other stapling or gummed tape is necessary in the employment of the carton. In order to complete the assembly 0! the carton, the members I and Bare bent along the fold-lines along the longitudinal edge of side walls 4 and 6 until they are at right angles thereto and then the flaps l2 and ii are bent along fold-lines and i5 and I8 and i1 until they are at right angles to cover sections 9 and i I at which position the flaps I2 and I3 are contiguous and slots IS- and 2| register with each other. the cones are put in position with bottoms of the core thereof in openings 38, the top covers are folded in a similar manner as the bottom covers in which case the holes 39 register with the tops of the cores of the cones being packaged.

The cartons described above are suitable or may be readily made suitable for the packaging of all sorts of articles including electric light bulbs.

It is to be understood that the foregoing detailed description and drawing is given merely by way of illustration and that many variations may be made therein without departing from the spirit of my invention.
